WIND-MOTOR.

SPECIFICATION forming part 0f Letters Patent N0. 664,374, datedDeCembel 25, 1900.

Application filed J'nne 25, 1900. Serial No. 21.460. (No model.)

lowing is a specification.

' This invention relates `to the construction of windmotors, and has been devised more especially for use inoperating the in usic-sheets of self-playing instruments.

The object of the invention has been not 4only to improve the construction of the m0- tors generally, but specially to render them steady and free from jerkiness in operation, so that the musicsheet may be given a perfectly even anduniform movement.

The nature of the invention is fully set forth below and will also be understood from the accompanying drawings', in whichm Figure 1 is an elevation, and Fig. 2 a plan, of my improved motor. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Figs. 4and 5 are sections on the lines 44 and 5 5, respectively, of Fig. 3. Fig. 6 is a perspective of the tubular valve employed.

In said drawings, 10 `10 -represent a series of pneumatics or power bellows arranged around a valve-block 11, in the center of which is a vertical rotating tubular valve 12, communicating with each pneumatic by a separate passage 13. The valveis open at its ends and is also divided at the center by a close or imperforate partition 14, so that one end becomes the inlet end and the other the discharge end of the valve.' The valve is cut away at opposite sides, so as to form a large inlet-port at 15 and a similar outlet-port at 16. The valve is supported upon a central vertical shaft 17, stepped at its bottom in a bearing 18, supported by the arms 19 from a surrounding metal cylinder 20, inserted in the block 11 and having slots registering with the passages 13. The shaft is made fast in partition 14, so that the valve and shaft necessarily rotate together, and the shaft is also provided with a top bearing 21, supported by the spider 22. At its upper end the shaft carries a combined crank, pulley, and balance-wheel 23, having a crank-pin 24,` to which all the pneumatics are united by conmeeting-bars 25 25, so that each pneumatic contributes its share of power to the operating of the wheel. The power is taken from the wheel by a belt (not shown) running in the groove 26 of the wheel. I prefer to make this wheel of sufficient weight and size, as shown, so that it will impart steadiness to the motion. The pneumatics are preferably arranged taugentially of and horizontally around the sides 28 standing vertically and parallel with the axis of the valve. This arrangement is very desirable with the rotating valve shown, as it places'all the pneu matics at the same distance from the valve, so that all work with the same quickness, and minimizes the eect of gravityon the moving sides.

In the operation of the device When the valve admits air to the passage 13 of any pneumatic it also closes the same passage against any discharge, and when it opens the passage to discharge it shuts on? entrance of fresh air, the valve thus alternating in its action with each pneumatic, so that each is alternately inflated and deflated, and by acting thus upon the pneumatics in successive order the desired rotary motion of the valve, shaft, and wheel is caused. The valve opens and closes the ports gradually, and thereby avoids imparting sudden impulses to the wheel.

While the arrangement of the pneumatics around the valve and shaft 17 with the hinges parallel to the axis of the valve is a very desirable one, I do not wish to be limited thereto except in such of my claims as expressly call for that arrangement, nor do I Wish to be limited to the vertical arrangement of the shaft and valve, nor to the use of four pneumatics, as obviously the number may be varied.

I claim- 1. The wind-motor, wherein are combined a series of Vpneumatics and a rotating valve located centrally of the pneumatics and controlling all of them, the moving side of the pneumatics swinging on hinges arrangedparallel with the axis of the valve, substantially as specified.

2. The wind-motor, wherein are combined a series of pneumatics and a rotating valve located centrally of the pneumatics and con-V trolling all of them, the pneumatics standing valve and with the hinges 27 of their movable tangentially of the valve-chamber and having the hinges of their moving sides arranged parallel with the axis of the valve, substantially as specified.

3, Thewind-rnotor, wherein are combined a series of pneumatics and a rotating valve connected to and controlling them, the moving Side of the pneumatics swinging on hinges arranged parallel with the axis of the valve,

substantial ly as speci iied.

4. The Wind-motor, wherein are combined a series of pneumatics, a shaftdriven bythe motor and va tubular valve mounted on the shaft, and acting to control all the'pneu matics, said valve being transversely divided into partition into an inlet portion and an outlet portion, substantially as specified.

7. The Wind-motor, wherein are combined a series of pneumatics and arotating tubular valve arranged centrally of the pneumatics and controlling all of them, one end of said valve controlling the admission and the other end controlling the exhaust of the air, and a valve block or casing having suitable air-passages 13 connecting the valve with the pneumatics, substantially as specified.

S. The wind-motor, wherein are combined a series of pneumatics and a rol ating tubular valve arranged centrally of the pneumatics and controlling all of them, said valve having a central partitionrand having its ends cut away at opposite sides, and a valve casing or block haVing'air-passages 13 connecting the ends of said valve with the pneumatics, substantially as specified.

9.- The Wind-motor, wherein are combined a series of pneumatics, a shaft driven by the motor, and a tubular valve mounted on the shaft and acting to control all the pneumatics, said valve being open at its ends, and divided transversely, into inlet and outlet portions, and said portions having alternatelyacting ports communicating with 'the passages leading to the pneumatics, substantially as specified.
